  • the heat of 302 is not directly transferred to the heater case support component 303 and the hot air outlet 400. Therefore, the heater case supporting component 303 and the hot air blowing part 400 receive a small amount of heat from the heater case 302, and the heat deformation of the heater case supporting part 303 and the hot air blowing part 400 can be prevented.
  • the heat-resistant cushioning material 600 is disposed between the heater case 302 and the heater case support component 303, and between the heater case 302 and the hot air blowing part 400, for example, washing is performed. It is possible to suppress rattling of the heater case 302, the heater case supporting component 303, and the hot air blowing part 400 due to vibration during dehydration of the object. Therefore, it is possible to prevent abnormal noise from being generated by the heater case 302, the heater case support component 303, and the hot air outlet 400.
  • the hot air blowing part 400 is fixed only to the front part 31 of the water tank 3, and the heater case support component 303 is fixed only to the rear part 32 of the water tank 3, the front part of the water tank 3 and the water tank 3 In combination with the rear part, the heater case 302 supported by the heater case support component 303 and the hot air blowing part 400 can be combined. Accordingly, assembly of the water tank 3 and the drying system 6 is facilitated, and the assemblability of the drum type washing machine of the present embodiment is high.
  • the drying system 6 is provided between the water tank 3 and the drum 4 below the plane including the central axis of the water tank 3 and including the horizontal axis orthogonal to the central axis.
  • the drying force between the tank 3 and the drum 4 is higher than the plane including the central axis of the water tank 3 and the horizontal axis perpendicular to the central axis.
  • Place part of system 6 May be.
  • a part of the drying system 6 is disposed between the aquarium 3 and the drum 4 on the left side of the plane including the central axis of the aquarium 3 and including the vertical axis perpendicular to the central axis. Also good.
  • a part of the drying system 6 is arranged between the tank 3 and the drum 4 on the right side of the plane including the central axis of the tank 3 and including the vertical axis orthogonal to the central axis. Also good. In short, the place where at least a part of the drying system 6 is arranged may be anywhere between the aquarium 3 and the drum 4.
  • the drying system 6 is disposed between the water tank 3 and the drum 4. Even if the entire drying system 6 is disposed between the water tank 3 and the drum 4. Good. In other words, all of the dehumidifying heat exchanger 100, the air blowing mechanism unit 200, the heating mechanism unit 300, and the hot air blowing unit 400 may be disposed between the water tank 3 and the drum 4.
  • the heat exchanger lOO for dehumidification is arranged between the water tank 3 and the drum 4, but it may be arranged between the outer box 1 and the water tank 3.
  • the convex portion 322 may be provided at the lower portion of the force water tank 3 provided with the convex portion 322 at the lower portion of the heater case 302. Specifically, a first hole is provided in a portion facing the water tank 3 with respect to the heater case support component 303, and a second portion protruding from the heater case 302 is directed to the portion facing the first hole with respect to the water tank 3. Providing a convex part with holes. In this case, the overheat prevention device 500 is inserted into the second hole, and the overheat prevention device 500 is brought into contact with the lower portion of the heater case 302.
  • the force that provided the hole 204 for passing the sheathed heater 301 in the blower mechanism unit 200 may be provided with the hole 204 for allowing the sheathed heater 301 to pass through the water tank 3. Yes.
  • the place where the hole 204 for allowing the sheathed heater 301 to pass therethrough may be the lower part of the front surface of the water tank 3 or the lower part of the rear surface of the water tank 3.
  • the axis of the washing and dewatering tank may be horizontal, inclined, vertical, or offset. That is, the axis of the washing / dehydrating tub may be parallel to the horizontal plane, may be inclined with respect to the horizontal plane, or may be perpendicular to the horizontal plane.

Abstract

La présente invention concerne une machine à laver et à sécher le linge capable de supprimer la sensation de gêne et de malaise ressentie par des utilisateurs et augmenter le rendement de séchage d’un chaque lessive sans entraîner d’augmentation de coût de production. Un réservoir d’eau (3) est disposé dans un boîtier extérieur (1). Un tambour (4) stockant le linge est disposé de façon rotative dans le réservoir d’eau (3). Une partie d’un système de séchage (6) destiné à sécher le linge dans le tambour (4) est installée entre le réservoir d’eau (3) et le tambour (4). Ainsi, l’enveloppe extérieure supérieure du boîtier extérieur (1) peut être empêchée d’être chauffée sans utiliser de matériau d’isolation thermique et au moins une partie de la chaleur rayonnante du système de séchage (6) peut être retenue dans le réservoir d’eau (3).
